OPERATING BASICS
SWITCHING POWER ON/OFF
1 Switch ON the DC power supply.
• If operating mobile, skip this step.
2 Press the (POWER) switch to switch ON the
transceiver.
3 To switch OFF the transceiver, press the (POWER)
switch again.
• In a fixed installation, after the transceiver has been
switched ON, it can then be switched OFF or ON by
using only the power switch on the DC power supply.
ADJUSTING VOLUME
Turn the VOL control clockwise (or counterclockwise) to
increase (or decrease) the audio level.
ADJUSTING SQUELCH
The purpose of the Squelch function is to silence
background noise output from the speaker (squelch
closed) when no signals are present. When the squelch
level is set correctly, you will hear sound (squelch
opened) only while a station is actually being received.
Turn the SQL control to just eliminate the background
noise when no signal is present.
• As you turn the control clockwise, stronger signals are
required to open the squelch.
Note:
The point at which ambient noise on a frequency just disappears,
called the squelch threshold, depends on the frequency.
SELECTING A BAND
Press
[BAND]
to select the VHF or UHF band.
